Hatch Pattern as an Name Object...

[Ahankhah]

Hello everybody,

as most of you know, a drawing file has tables containing linetypes, etc. so there is no need to have acad.lin or acadiso.lin to get definition of loaded linetypes.

I find out this is also correct for hatch patterns, i.e. if you use a hatch pattern to hatch a boundary, even after deleting the HATCH object, definition of the pattern remains in the drawing.

 

My questions are:

 

1- How is it possible to get these hatch pattern definitions? (for linetypes AutoLISP functions (tblobjname), (tblnext), etc. work well, but for patterns not.)

 

2- How can one purge them out of drawing?

 

Thanks in advance
